Rapid complete atrioventricular heart block reversal due to Lyme carditis

Congenital complete heart block is defined as a complete atrioventricular block occurring prenatally, at birth, or within the first month of life. Congenital complete heart block has a high mortality rate, and in infants with normal heart morphology, it is often associated with maternal connective tissue disease. In these latter cases, neonatal congenital complete heart block is usually irreversible. We present a rare case of a female neonate who had bradycardia noted at a gestational age of 37 weeks. Her mother had no autoimmune disease history. She had no structural heart disease, and the serology surveys for autoantibodies including SSA/Ro and SSB/La were all negative. Without intervention or medication, her congenital complete heart block completely recovered to a normal sinus rhythm within 5 days. The cause of the transient congenital complete heart block was unknown in this case.

Abstract A young child presented with hepatomegaly, ascites, and bradycardia in the setting of coronavirus disease-2019. Permanent complete atrioventricular block and severe right heart failure were diagnosed. He was treated with surgical epicardial pacemaker implantation. This report is the first description of coronavirus disease-2019–induced permanent complete atrioventricular block in a child.

Complete Atrioventricular

We have described several cases of complete heart block on the background of rheumatism ("Ter. arch", 1955), and both favorable and unfavorable clinical course. In all cases, an electrocardiographic break was noted in the passage of the pulse from the atria to the ventricles, when the atria and ventricles contract independently of each other. Some authors believe that the life expectancy of patients with complete atrioventricular heart block of rheumatic etiology does not exceed 2-3 years.

Tetralogy Of Fallot Repair

Tetralogy of Fallot (TOF) is the most common form of cyanotic congenital heart disease beyond the age of 3 months. Complete heart block (CHB) is rare but a serious sequalae post-repair of TOF. We present a case of an 18-month-old child who developed late CHB after around 1 year of the corrective surgery of the congenital anomaly. On the regular follow-up visit, the patient assessment was unremarkable. However, there was bradycardia, 55 beats/min. The ECG showed complete atrioventricular dissociation. Echocardiogram was done and demonstrated severe tricuspid regurgitation (TR). The patient required a permanent pacemaker and he is currently well. We are presenting this case as a late unexpected CHB, with a possibility of progressive right-side dilatation as a contributing factor to CHB due to severe TR.
